Multiple miscarriage

I have had 3 miscarriages with the last one being last week. I was 15w3d and went to do a 4d ultrasound for gender and that is how I found out. I was scheduled for D&C the very next day. How long did it take for everyone to get back to wanting to TTC. I'm not getting any younger I will be 37 next month and my husband is 31. I have one 17yr old. But I really wanted this baby. This is my 2nd loss in 6 months. The other happened back in 05. I'm not sure what my next steps should be. I'm still so heartbroken.
